The cave was discovered by a local man in 2005 and 5 first km of this cave was explored by explorers from British Cave Research Association in 2005, the whole 31 km was explored and publicly announced by the British cave explorers.

This cave is 31 km long, longer than Phong Nha Cave which had been considered the longest cave in this national park. The height can reach to 100 m and 150 wide. The limestone formation is also more spectacular than that of Phong Nha Cave. The British cave explorers was impressed by the beautiful and spectacular stalactites and stalagmites inside this cave and they named it Thiên Đường Cave (Paradise Cave).In 2012, a new scorpion species Vietbocap thienduongensis was found here. Paradise cave is just allowed 1000m for visitors, 7000m deep more for adventurer.

Dark cave is amazing and the true experience, kayaking over the river to get there, walking through the dark with only the head touch on your mining helmet, having a mud fight in the mud baths deep in the cave and then washing clean with a swim in the lake inside the cave.

Maybe its the unfathomable amount of time, maybe it’s the natural process of erosion and the complete absence of human intervention. Maybe it’s that caves are only starting to be discovered on a planet where humans have existed for thousands of years. Walking through, or swimming through, all of the caves in Phong Nha Ke Bang national park is definitely highlight of Vietnam.

With naturally primitive features, Paradise Cave looks like a landscape painting, making it very attractive to visitors. According to spelunkers, the deeper one journeys into the cave, the more one feels the wells of heavenly clarity all around. There are a series of white crystal stalactites resembling glass pillars and many other spectacular formations.

Phong Nha cave is not only a natural legacy of the world or a wonder of the country Vietnam, but also a relic system of the historic street Ho Chi Minh which collaborates with Xuan Son Ferry in order to create a route supporting for the battleground of the South Vietnam during US War. Today, this place has become the first section of Ho Chi Minh trails. Therefore, coming to Phong Nha means you are visiting this legendary trails.
